MECHANISIVI-FOR GUIDING THE EDGES OF TEXTILE WEBS.

SPECIFICATION forming part of Letters Patent No. 463,584, dated November1'7, 1891. Application filed October 7, 1886. Serial No. 215,627. (Nomodel.)

T0 @ZZ whom t may concern.-

Be it known that I, SOCRATES 'SoHoLFIELn a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Mechanism forGuiding the Edges of Textile lVebs, of which the following is aspecicat-ion.

In feeding Webs of cloth to cloth-finishing machines it is verydesirable to have the fabric fed into the machine in such a manner thatthe edges ot' the web will run in a true line, and it is the object ofmy invention to provide an improved automatic mechanism for properlyguiding thevsaid edges; and my invention consists in a guide-rollerheldupon a roller-support which is adapted for angular movement to changethe direction of the axis of the guide-roller and reversing devices inoperative connection with the roller-support, in combination with adriving means for the reversing devices and a bearing for the drivingmeans, from which, as a resisting base, movement is imparted to thereversing devices, the said bearing being independent of the angularmovement of the 1'ollersup port, and also in the combination therewithof a supplementary guide for the edge of the web, and in the improvedconnection between the reversing devices and the roller-support.

In the drawings, Figure l is a plan of a webguiding machine embodying myimprovement, the running edge of the web being indicated by the brokenline. Fig. 2 represents an elevation of the machine taken from the sideat which the web is to enter the same. Fig. 3 represents au elevation ofthe machine taken from that side which is directed toward the axis ot'the web. Figs. 4, 5, and 6 are detail views, illustrating the preferredconstruction of the reversible mechanical movement. Fig. 7 is a planshowing the application of my improvement to a package inding machine.Fig. 8 is a Vertical section taken in the line x of Fig. 7. Fig. 9 is adetail view showing a modification of the supplementaryguide for holdingthe edge of the web back to the true line. Fig. IO represents a sectiontaken in the line x :c of Fig. l0, showing also the end of thesupplementary guide. Figs. 1l, 12and 13 are detail views illustratingmodifications of the supplementary guide and the projectingpivot-supported guide-rollers.

In the accompanying drawings, A is the movable frame ot the web-guidingmachine.

b B are projecting guide-rollers, the peripheries ot which are set withspurs of wire, as in the rollers of loom-tem ples, the said projectingguide-rollers being arranged to turn loosely upon the studs C O, whichare securely held in the head D, the said head being pivL oted totheframe A by means of a downwardly-extending stem, which passes through acentral perforation in the hub a of the frame, and also provided with agear E, a segment of which engages with the Worm F, se-

cured to the shaft G, so that upon turning the shaft G angular movementwill be imparted to the head D and rollers B B. The head D is alsoprovided with the projecting bars II II, which are arranged at oppositesides of the rollers B and parallel with the same, and which serve toguide the edge portion of the web along the arc of a segment of eitherof the rollers B, as most suitable.

The head D, which carries the rollers B, is secured loosely to the hubtt of the frame A by means of the screw h and washer c, the screw l)being made to enter the lower end of the pivot-stern of the head D.

'Upon the shaft G, which turns in the bearings d d of the frame A, isloosely placed the vibrating lever I, from which operative connectionvismade to the eccentric J upon the driving-shaft K by rod L, the saidshaft K being heldin the bearing a4, which constitutes a resisting basefor the opposite action of the eccentric J upon the lever I through theintervening connecting-rod L. At the upper end of the vibrating lever Iare secured' the loose ratchetcatches M M', by means of the screw-studse e, and to the lower end of the said lever is vsecured the flat springil, having' a triangular head or engaging endf.

Adjacent to the lever I on the shaft G is secured the ratchet-wheel O,and at the opposite side of the said ratchet-wheel on the shaft G islooselyplacedtheratchet-guard P, which is provided at the lower side ofits edge with the V-shaped notches g g', which are adapted to receivethe upper or engaging edge of the means of the connecting,

IOO

angular head f of the spring N, and at the up'- per side of its edgewiththe notches It 7L', which are adapted to receive the lower or engagingedge of the ratchet-catches M M', respectively, and allow them to engagewith the teeth of the ratchet-wheel O upon the proper movement of theguard P, which, through the action of the spring N, pai-takes of thevibrating movement of the lever I, except when the normal movement ofthe guard P with the lever I is obstructed by the action of thedetector-lever R, so as to throw the engaging angle of the head f of thespring Nout of the notch g or g', the case may be, into its oppositenotch.

Upon the edge of the guard P, at a point between the notch g and theadjacent notch h, is placed the guard-regulating plate Q, which isprovided with the offset-slot t', and is secured to the edge of theguard by means of the screwsjj. The slot i is adapted to receive thelaterally-moving end 7a of the detector-lever R, and the distance fromthe shoulder l to the end 'm of each arm of the oset-slot is properlymade equal to the vibrating movement imparted to the periphery of theguard P, through the actionof the spring N and its engaging notch, plusthe thickness of the end k of the lever R, the said lever beingsupported in the lateral slot n made in the stand S against movementwith the regulating-plate Q upon contact therewith. The detector-lever Risloosely pivoted between the center pointed screws o o, and is providedat its end p with attached guideplate q,which presents a comparativelybroad surface to t-he edge of the web, and at the back of the said leveris placed the slight wire spring u., which serves to hold the guide in aforward position. The ratchet-wheel O of the reversing mechanicalmovement may be termed the reversible member and the vibratingratchetcatches M M and the vibrating guard P the engaging member, thesaid members constituting essential features of a mechanical movementfor oppositely changing thedirection of the action of a machine inaccordance with the controlling movement of a detector or governor; butin carrying out my invention I do not limit myself to reversing devicesof ratchet construction, butincl udein the term reversing devices in theclaim the reversible and engaging devices of whatever nature, which areemployed instead of ratchet devices, for automatically reversing theaction of a machine, the particular construction of the reversible andengaging members not constituting an essential feature of my im`provement.

The frame A, when arranged in a working machine, may be secured-to afiat holding-bar T, which vis provided with a slot fu, adapted for thelateral adjustment of the frame A and its attached mechanism by means ofa thumbscrew s and clamping-nut t.

Upon the rod U, Fig. 7, which forms a fixed portion of the machine towhich my improved web -guiding mechanism is attached, and around aportion of the periphery of which the web is made to pass, is placed theadjustable guide V, which is to be set in the true guiding-line for theedge of the web, which is nearer than the guide-plate q tothe axis ofthe said web.

The guide V, instead of being attached to the rod U, which is separatefrom the frame A, may be attached to au said fra-me and may be made ofany form of construction adapted to hold the edge of the web slightlyback from its outward position at the detector-guide q, to the face ofwhich extension of the it is brought by means of the action of the vroller B, when properly inclined to the axis of the web, by the actionof the power-dispensing mechanical movement. The line followed by theedges of a web, when in a packaging winder provided with my improvedweb-guiding machine, is shown in Figs. 7 and 8, the edge o of the web YVfirst passing from the loosely-folded pile w over the rod X, between theedge guides V V', thence passing over the projecting bars Il Il andunder the intermediate roller B, being thus guided around the lowerportion of the periphery of the said roller, and lthence inwardly to thetrue-line guide V and onto the packaging-roll Y, touching in its coursethe face of the detectorguide q, the movement of which by means of thespring u and the edge of the web will cause the required variation orchange in the angle of the axis of the roller` B with the axis of theweb. lllhenever the edge o fails to touch the face of the detector-guideq, tector-lever R will be thrown by the action of the spring il, intoline with the upper portion of vthe offset-slot i, thus controlling therelative vposition of the vibrating movement of the guard P with thelever I, so that the the end k of the def IOC ratchet-catch M will becaused to enter the notch h of the guard and to engage with the teeth ofthe ratchet-wheel O to turn the said ratchet-wheel O, shaft G, and wormFl in the direction of the arrow shown in Fig. 3, thus causing theangular movement of the wormgear E, head D, and the attached roller B inthe direction of the arrow shown in Fig. l, until the roller B hasbecome sufficient-ly inclined to the axis of the web to cause the edgeof the web to be forced against the face of the detector-guide qsufficiently to cause the end 7tof the lever R to be brought to anintermediate position in the slot u of the stand S, in which positionthe catches M M will be prevented from action upon the teeth of theratchet-wheel O to turn the worm F, and thus vary the inclination of theroller B. By reason of the lifting action of the guard P upon the saidcatches, and in case the said roller has been moved so far as tosubsequently cause the edge 'u' of the web by its pressure against theface of the detectorguide q to force the end 7c of the detector-lever Rinto the line of the lower portion of the 'slot fi, then the head f ofthe bearingspring N will be shifted over to the notch g', thus changingthe relative position of the guard P and the catches M M', so that thecatch M will now be brought into action upon the ratchet-teeth of thewheelO to causea reverse movement of the head D and roller B,

" which will have theeffect of drawing the edge of the web back untilthe lever Ris again brought to the intermediate point, at which pointthe vibrating catches M M will cease to act upon the teeth of theratchet-wheel. The edge v of the web, as shown in Fig. 7, is carried bythe action of the inclined roller B slightly beyond the properrunningline for guidance upon the rolled package Y, and is brought backto the said line and there held by means of t-he stationary guide V.'lhus the necessary slight variation in the action of the roller B uponthe edge of the web will be corrected by the guide V.

The duplicate rollers B B (shown one above the other in Figs. 2 and 3)are adapted for action upon both edges of the web at the same time, asis desirable in the case of a longitudinally-folded web, one of the saidedges being made to pass under the upper roller B and the other to passover the lower roller; but for guiding a single edge either of therollers B may be used, as most convenient. The shaft G is to befrictionally held from being turned in either direction by the normalvibration of the lever I not accompanied with the engagement of one ofthe catches with ratchet-wheel, and this may be desirably accomplishedby means of the spring la', which is attached to the upper side of theframe A and presses against the ends of the teeth of the ratchet-wheelO.

The guide V (shown'in Figs. 7 and 8) is simply a flanged collar held inposition upon the rod Uby means of an adjusting-screw o4; but in somecases it is desirable to clasp both sides of the web at its edge, andsuch a guide is shown in Figs. 9 and 10, the laterally-projectingportion t/ being slotted, as shown in end View, Fig. lO, and by dottedline in Fig. 9. The edge of the web will thus be prevented from curlingover at the guide, the slot a being properly made about the width of thethickness of the cloth, or, instead of a slotted device, spring-pressuremay be brought to bear upon the surface of the web at and near theguided edge of the same for this purpose, as in Fig. 13, which shows theflat spring a2 secured to the projecting portion of the guide by meansof the screw h2 and having an opening .2 between the spring a2 and theprojecting lip a3 for the insertion of the edge of the web.

The slotted guide V (shown in Figs. 10 and 11) may be constructed asshown in Figs. 12 and 13, in which the guide V is shown as attached to aloosely-held pivot-rod U so that the slotted portion y may move up anddown with theoval surface of the package Y, and

in this manner the ends of the package will be wound up true and even.

Instead of the rollers B set with spurs, as shown and described, rollershaving any suitable friction-surface may be employed and arubber-covered or other frictional surface for securing a firm lateralhold upon the fabric, and may be held in firm contact therewith.

My improvement may be advantageously employed without the guide V, whichguide is more especially desirable in feeding cloth to drying andtentering machines in which the edge of the web must be fed to the hooksor clips in a true line; but for other ordinary purposes the said `guidemay be omitted, the automatic regulating movement of the pivoted rollerB or its equivalent serving to keep the edge of the web sufficientlynear to the true line.

The shaft K, Fig. 7, which serves to operate the power-dispensingmechanical movement, is driven from the shaft d of the windingmachine bymeans of the pulleys d and e and the connecting-band c.

I am aware that a swiveling bracket having a feeler jointed thereto forbearing against the edge of the web, and a feed-roller adapted formovement with the swiveling bracket are shown and described in EnglishPatent No. 3,239 of 1882, in combination with a reversing mechanicalmovement actuated by the rotary movement of the feed-roller, which hasits axis supported by the swiveling bracket, so

as to move angularly therewith. Therefore I' make `no claim thatincludes a reversing me- IOO chanical movementv having its drivingroller or shaft supported by the swiveling bracket Y and adapted forangular movement therewith, as shown in said Letters Patent; but in myinvention the reversing devices which serve to change the direction ofthe axis of the guide-roller are actuated by means of a shaft or itsequivalent driven roller having a bearing, from which, as a resistingbase, the power is applied to the reversing devices, the said bearingbeing independent of the angular movement of the support for theguideroller.

I claim as my invention* 1. The combination, with a guideroller adaptedto guide the movement of the edge of the web, a roller-support which isadapted for angular movement to change the direction of the axis of theguideroller,and reversing devices in operative connection with the saidroller-support, of a driving means for actuating the reversing devicesand a bearing for the driving means, from which as a resisting base thepower is applied to the reversing devices, the said bearing beingindependent of the angular movement of the roller-support, substantiallyas described.
